I'm going to trade my TSl in this weekend, It hasn't worked correctly since I bought it. I had a show Sat. night and during set up I kept blowing the main fuse. I don't even want to try to fix it. I'm 150 miles from the nearest repair shop and it's just not worth it. I don't think that I would feel confident going on stage with this amp again. So I was told from Sam Ash that they would trade up to a JVM 210H, but I don't know anyone who has used one.
